SPECIFICATION.

I, DAVID GULVER, of Kingston, in the county of Luzerne and State of Pennsylvania, have invented a new and useful Improvement in Plows. The following is a full and clear statement of the same, reference being had to the accompanying drawing making a part of this specification.

My invention has for its object to furnish a plow which shall be reliable and efficient in operation, simple in construction, and durable in use; and it consists in the construction and com binat-ion of parts as hereinafter more fully described and pointed out by the claim.

Figure 1 is a perspective looking from the top, and showing the insides of the moldboards a a, with their shares 1) b attached in the usual manner. Fig. 2 is a longitudinal section taken through line y 3 Fig. 1.

These boards are constructed with heavy wroughtiron screw-bolts running from their upper stems c c, which are cast solid into the boards when made. They are secured to a slotted beam, 01, with heavy washers and burrs.

The slots 6 e are intended to allow the plow to be made narrow or wide to suit any desired width of plantin g and at the same time allow the mold-boards to be thrown close or far apart at their points, or, in fact, turned into any desired position. They are now shown ready to plow toward a row of corn, but may be changed so as to throw the earth away from the row by simply removing them from the slots 6 e and placing them-into the holes ff, when they form an ordinary double-mold-board plow to be used between the rows, or astride, to plow the earth awa-yfrom the roots. In order to favor the various changes to which this plow is adapted, and at the same time make it permanent, there are two braces, g g, securely bolted to the side of the tongue h, and attached to the cross-beam d. On the tongue is placed a slotted plate, '5, made of iron, through which a bolt and handburr, j, secures the double-tree or pullin g-beam k. The slotted plate admits of taking up all lost motion by allowing the pulling-chains Z l to be drawn tight, which are attached to the mold-hoards by means of a clasped link, which can move around them and adjust itself in any position. It is intended that the chains shall sustain all the draft necessary to move the plow, and the bolt and hand-burr simply hold the beam snugly against the tongue. On the back end of the tongue, and attached to the cross-beam d, is a cast-iron plate, m, having an ear on each side of the tongue, and a A-shaped ridge running across its face. Inside a notch to suit this is cut out across the tongue. This iron is embedded into the beam, and a strap of iron running across it and coming up through the tongue is secured by a burr to each side. By this method of fastening the tongue it will be seen that to raise the front it is necessary to screw the hind burr down and loosen the front one up; and to change the position of the tongue, in the opposite direction the other burr must be used. This is a very simple and effectual way of regulating the depth of the out to be taken in plowing, and at the same time securingfirmlythetongue andcross-beam. The handles of the plow a n are thrown to one side to enable the plowman to walk in the furrow.

Having thus clearly explained the construction of this plow and pointed out the manner of using the same, what I claim as my invention, and desire to secure by Letters Patent, is- I The block m fitting in the cross-beam d and upon each side of the tongue h, and held in place by suitable clamp-bolt, substantially as and for the purpose set forth.
